Description

Disclosed embodiments relate to sanitary washing devices.

In order to prevent dirt from adhering to the bowl portion of the toilet bowl, a pre-cleaning technique is known in which the bowl portion of the toilet bowl is wet with cleaning water before the user uses the toilet bowl.

For example, there is a local cleaning device in which a nozzle for pre-cleaning is provided with a jet port for pre-cleaning, and the flow path inside the nozzle is shared by the jet port for local cleaning and the jet port for pre-cleaning ( For example, see Patent Document 1). In this local cleaning device, while preserving the cleaning water ejected from the nozzle for local cleaning at the storage position of the nozzle with the cover body inside the device, pre-cleaning is performed using the cleaning water ejected from the nozzle for pre-cleaning. I do.

There is also a local cleaning device in which the nozzle for pre-cleaning is provided separately from the nozzle for local cleaning (
See, for example, Patent Document 2). In this local cleaning device, a nozzle for local cleaning is arranged at the rear center of the bowl portion, and a nozzle for pre-cleaning is arranged at the side thereof.

JP-A-6-322806 JP, 2008-223467, A

However, it is difficult for the conventional local cleaning apparatus in which the nozzle for local cleaning is provided with the jet port for pre-cleaning to advance the nozzle to perform pre-cleaning. This is because the washing water ejected from the jet for local washing can be suppressed only when the nozzle is stored, so if the nozzle is advanced and pre-washing is performed, the local washing will be performed before the user's toilet. This is because the cleaning water is spouted from the water ejection port to the user's local area. As described above, this local cleaning device has a problem that it is difficult for the cleaning water to reach the front side of the bowl because it is difficult to advance the nozzle to perform the pre-cleaning.

Further, in the conventional local cleaning device in which the nozzle for pre-cleaning is provided separately from the nozzle for local cleaning, since the nozzle for pre-cleaning is arranged at a position laterally displaced from the rear center of the bowl part, There is a problem in that it is difficult for the cleaning water to reach the side opposite to the side where the pre-cleaning nozzle is arranged.

In accordance with a command from the VB550, the supply destination of the wash water or the sterilizing water is the first jet port 211, the second jet port 212 or the third jet port 213 of the human body jet port 210, the toilet jet port 220 or Switch to the nozzle cleaning chamber 140.

The control unit 600 is, for example, a CPU (Central Processing Unit). Control unit 60
0 reads and executes a program stored in a storage unit (not shown)
The sanitary washing device 20 is operated by controlling the flow path switching unit 520, the heat exchanger unit 530, the electrolytic cell unit 540, the nozzle driving unit 120, and the switching valve 130. The control unit 6
00 may be configured only by hardware without using a program.

Next, a specific processing procedure of the above-mentioned pre-cleaning and after-cleaning will be described with reference to FIG. FIG. 10 is a flowchart showing the procedure of pre-cleaning and after-cleaning. It should be noted that FIG. 10 shows only the processing procedure of the processing relating to the pre-cleaning and the after-cleaning, and omits the processing procedure of other processing such as local cleaning and discharge of waste.

As shown in FIG. 10, the control unit 600 determines whether or not the entry detection sensor 24 detects entry of the user (step S101). If the user's entry is not detected (step S
101, No), the control unit 600 repeats the process of step S101 until the entry detection sensor 24 detects the entry of the user.

When it is determined in step S101 that the entry sensor 24 has detected entry of the user (step S101, Yes), the control unit 600 controls the nozzle driving unit 120 to advance the cleaning nozzle 150 to the target position (step). S102). After that, the control unit 600 spouts the washing water from the toilet outlet 220 of the washing nozzle 150 (step S103).
..

The process of step S103 will be specifically described. First, the control unit 600 controls the flow path switching unit 520 to switch the supply destination of the cleaning water to the electrolytic cell unit 540 and also controls the switching valve 130 to control the cleaning water. To the toilet outlet 220. This allows
A flow path is formed from the water supply source to the toilet jet outlet 220 via the electrolytic cell unit 540.

Further, the control unit 600 does not energize the electrolytic bath of the electrolytic bath unit 540 so that the electrolysis bath unit 540 does not electrolyze the wash water. As a result, the room-temperature cleaning water is supplied from the electrolytic cell unit 540 to the toilet spout 220, and the room-temperature cleaning water is jetted from the toilet spout 220 to the bowl 11.

As described above, in the sanitary washing device 20 according to the first embodiment, pre-washing is performed with the washing nozzle 150 advanced, so that washing water can be supplied to the entire dirt adhering region B2 ( (See FIG. 8). Therefore, it is possible to effectively suppress the adhesion of dirt to the bowl portion 11. The pre-cleaning performed in the state where the cleaning nozzle 150 is advanced as in step S103 is referred to as “advance pre-cleaning”.

Subsequently, the control unit 600 controls the nozzle drive unit 120 to retract the cleaning nozzle 150 to the storage position inside the case unit 21 (step S104). Then, the control unit 600
Similar to step S103, normal-temperature cleaning water is jetted from the toilet nozzle 220 of the cleaning nozzle 150 to the bowl 11 via the electrolytic cell unit 540 (step S105).

As described above, in the sanitary washing device 20 according to the first embodiment, in addition to advance pre-washing, pre-washing with the washing nozzle 150 accommodated is also performed. As a result, the cleaning water can be more reliably supplied to the rear side of the bowl 11 where dirt is likely to concentrate. The pre-cleaning performed in the state where the cleaning nozzle 150 is stored as in step S105 is referred to as “storage pre-cleaning”.

The order of advance pre-cleaning and storage pre-cleaning may be reversed. That is, the control unit 600
Alternatively, the pre-cleaning may be performed with the cleaning nozzle 150 housed, and then the pre-cleaning may be performed with the cleaning nozzle 150 advanced.

Subsequently, the control unit 600 determines whether or not the seating detection sensor 25 detects the seating of the user within a predetermined time from the detection of entry into the room (step S106). In this process, when it is determined that the seating detection sensor 25 has detected the seating of the user (step S106, Yes).
The control unit 600 determines whether or not the seating detection sensor 25 detects the seating, specifically, whether or not the seating of the user is not detected (step S107).

When the user's leaving is not detected (step S107, No), the control unit 600 repeats the process of step S107 until the seating detection sensor 25 detects the user's leaving. The user's urination is usually performed during this period.

When it is determined in step S107 that the seating detection sensor 25 has detected the user's leaving (Yes in step S107), the control unit 600 detects whether or not a predetermined time has elapsed since the sitting was detected. (Step S108). When the predetermined time has not elapsed (step S108, No), the control unit 600 repeats the process of step S108 until the predetermined time elapses. Although illustration is omitted here, normally, during this period, the waste material in the bowl portion 11 is discharged.

When the control unit 600 determines in step S108 that the predetermined time has elapsed after the separation is detected (Yes in step S108), the cleaning nozzle 150 is stored and the bowl portion is discharged from the toilet outlet 220. Sterile water is jetted to 11 (step S109).

The process of step S109 will be described in detail. First, the control unit 600 controls the flow path switching unit 520 and the switching valve 130, respectively, from the water supply source to the toilet outlet 220 via the electrolytic cell unit 540. Form a flow path to reach. In addition, the control unit 600 energizes the electrolytic cell of the electrolytic cell unit 540 to generate sterilizing water. As a result, the sterilizing water is supplied from the electrolytic cell unit 540 to the toilet jet outlet 220, and the sterilizing water is jetted from the toilet jet outlet 220 to the bowl portion 11.

As described above, by performing the after-cleaning with the sterilizing water in the state where the cleaning nozzle 150 is housed, the sterilizing water can be supplied to the bacterium propagation region B1 (see FIG. 7). Therefore, the growth of bacteria in the bowl 11 can be effectively suppressed.

When the processing of step S109 is completed, or when the seating detection sensor 25 does not detect the seating of the user within a predetermined time from the detection of entering the room in step S106 (step S1).
06, No), the control unit 600 ends the series of pre-cleaning and after-cleaning processes for one toilet operation. After that, the control unit 600 restarts the process from step S101.

As described above, the sanitary washing device 20 according to the first embodiment includes the case portion 21, the washing nozzle 150, the switching valve 130, the nozzle driving portion 120, and the control portion 600.
The cleaning nozzle 150 is housed in the case portion 21, and is a human body ejection port 210 that ejects water toward the user's local area and a toilet ejection port 220 that ejects water toward the bowl portion 11 of the toilet bowl 10.
Equipped with. The switching valve 130 supplies the water to the human body outlet 210 or the toilet outlet 220.
Switch to. The nozzle driving unit 120 advances the cleaning nozzle 150 toward the bowl unit 11 or retracts the cleaning nozzle 150 toward the case unit 21. The controller 600 controls the switching valve 130 and the nozzle driver 120.

Further, the control unit 600 causes an advancing cleaning operation of ejecting water from the toilet outlet 220 toward the bowl 11 with the cleaning nozzle 150 advancing into the bowl 11. Therefore,
According to the sanitary washing device 20 according to the first embodiment, the bowl portion 11 can be wet in a wide range.

(Second embodiment)
Next, a second embodiment will be described. In the second embodiment, a modified example of the above-described pre-cleaning processing procedure will be described with reference to FIG. 11. FIG. 11 is a flowchart showing a modified example of the pre-cleaning processing procedure. Since the processing of steps S201 to S204 shown in FIG. 11 is the same as the processing of steps S101 to S104 shown in FIG. 10, description thereof will be omitted here.

In the above-described first embodiment, an example in which the storage pre-cleaning is performed after the cleaning nozzle 150 is retracted in step S104 and before the seating of the user is detected in step S106 has been described. However, the storage pre-cleaning may be performed, for example, after the seating of the user is detected.

Specifically, as shown in FIG. 11, after the cleaning nozzle 150 is retracted in step S204, the control unit 600 detects whether or not the seating detection sensor 25 detects the seating of the user within a predetermined time from the detection of entry into the room, for example. It is determined whether or not (step S205). Then, when it is determined that the seating detection sensor 25 detects the seating of the user (step S205, Yes), the control unit 60.
0 carries out pre-washing, that is, spouts wash water from the toilet outlet 220 toward the bowl 11 (step S206).

The processes after step S206 are the same as steps S107 to S109 in FIG.
If the seating detection sensor 25 does not detect the seating of the user in step S205 (No in step S205), the control unit 600 ends the series of pre-cleaning and after-cleaning processes.

In this way, the storage pre-cleaning may be performed after the user sits down. As a result, pre-cleaning can be performed as soon as possible for the user's toilet, so that the adhesion of dirt to the rear side of the bowl 11 where dirt is likely to be concentrated can be suppressed more effectively.

In addition, here, the start condition of the advance pre-cleaning is defined as the detection of the user entering the room,
The start condition of the advance pre-cleaning is not limited to the entrance detection. For example, the control unit 600 may start the next advance pre-cleaning on condition that the elapsed time from the previous advance pre-cleaning has reached a predetermined time. That is, the control unit 600 may regularly perform advance pre-cleaning regardless of whether or not the user has entered the toilet room, in other words, regardless of whether or not the user uses the toilet bowl 10. ..

Further, the advancing distance of the cleaning nozzle 150 in the advance pre-cleaning may be shorter than the maximum value of the advancing distance of the cleaning nozzle 150 in the local cleaning. Thereby, even if the time from the user's entry to the toilet is unexpectedly short, for example, it is possible to prevent the situation in which dirt adheres to the advanced cleaning nozzle 150.

For example, in FIG. 8, the cleaning nozzle 1 is separated by the same distance as the maximum value of the advance distance in the local cleaning.
The supply range C2 when 50 is advanced is shown. The controller 600 may shorten the advancing distance of the cleaning nozzle 150 in the advancing pre-cleaning to such an extent that the front end of the supply range C2 coincides with the front end of the dirt adhesion region B2.

Further, the advancing distance of the cleaning nozzle 150 in the advance pre-cleaning may be longer than the maximum value of the advancing distance of the cleaning nozzle 150 in the local cleaning. For example, the control unit 600 may advance the cleaning nozzle 150 to the limit value of the advance distance of the cleaning nozzle 150 and perform pre-cleaning. As a result, the cleaning water can be supplied to a wider area of the bowl portion 11.

Further, here, an example in which advance pre-cleaning and storage pre-cleaning are performed as pre-cleaning has been shown, but the control unit 600 may perform advance pre-cleaning twice. For example, the control unit 600 is
After the seating detection in FIG. 11 (step S205, Yes), the pre-cleaning is performed by advancing the cleaning nozzle 150 so as to be shorter than the advancing distance of the cleaning nozzle 150 in step S202, specifically, to such an extent that it does not reach the falling dirt. Good.

Further, in the above-described example, the advance pre-cleaning and the storage pre-cleaning are performed using the cleaning water, but sterilizing water may be used for the advance pre-cleaning and the storage pre-cleaning. In addition, the control unit 6
For 00, advance pre-cleaning may be performed only once as pre-cleaning.

(Third Embodiment)
Next, a third embodiment will be described. In the third embodiment, a modified example of the above-mentioned after-cleaning processing procedure will be described with reference to FIG. FIG. 12 is a flowchart showing a modification of the processing procedure for after-cleaning. The process before step S301 in FIG. 12 is the same as the process in steps S101 to S105 shown in FIG. 10, for example.

In the first embodiment, the example in which the after-cleaning is performed once has been described, but the control unit 6
00, after-cleaning may be performed multiple times. For example, the control unit 600 may perform the first after-cleaning using the cleaning water (step S303 in FIG. 12) and the second after-cleaning using the sterilizing water (step S305 in FIG. 12) as the after-cleaning. Good.

Specifically, as shown in FIG. 12, when the control unit 600 determines that the seating detection sensor 25 has detected the user's seating (step S301, Yes), whether the seating detection sensor 25 has detected leaving the seat. It is determined whether or not (step S302). When the user's leaving is not detected (step S302, No), the control unit 600 repeats the process of step S302 until the seating detection sensor 25 detects the user's leaving.

When it is determined in step S302 that the seating detection sensor 25 has detected the user's leaving the seat (step S302, Yes), the control unit 600 stores the cleaning nozzle 150 and the bowl portion 11 from the toilet outlet 220. The washing water is spouted to (step S303). That is, the control unit 600 controls the electrolytic cell unit 5 as in step S103 and step S105.
The washing water at room temperature is jetted from the toilet jet outlet 220 of the washing nozzle 150 to the bowl portion 11 via 40.

Subsequent steps S304 and S305 are the same as steps S108 and S109 described above.
Since it is the same as, the description will be omitted. If the seating detection sensor 25 does not detect the seating of the user in step S301 (No in step S301), the control unit 600 ends the series of pre-cleaning and after-cleaning processes.

In this way, after the user leaves the seat, that is, after the user's stool, by performing the after-cleaning in the state where the cleaning nozzle 150 is housed, the rear side of the bowl 11 where dirt is likely to concentrate is intensively cleaned. can do. That is, the cleaning power on the rear side of the bowl 11 can be increased. In this case, in order to further enhance the cleaning power, the control unit 600 controls the switching valve 130 so that the flushing water at a flow rate higher than the flow rate of the sterilizing water at the time of after-cleaning in step S305 is used for the toilet outlet 220. May be spouted from.

In addition, here, the example in which the detection condition of the user's separation is used as the start condition of the after-cleaning has been described, but the start condition of the after-cleaning is not limited to the detection of the separation. For example, the control unit 600 performs after-cleaning on the condition that the entry detection sensor 24 detects the exit of the user from the toilet room, specifically, the entry detection sensor 24 no longer detects the user. May be.

Further, here, an example in which the after-cleaning is performed with the cleaning nozzle 150 accommodated is shown, but the after-cleaning may be performed with the cleaning nozzle 150 advanced. In this case, the control unit 600 may perform the after-cleaning by advancing the cleaning nozzle 150 to a limit value of the advancing distance of the cleaning nozzle 150, which is longer than the maximum value of the advancing distance of the cleaning nozzle 150 in the local cleaning. .. Thereby, the sterilizing water can be supplied to a wider area of the bowl portion 11. Further, the control unit 600 may thereafter perform after-cleaning again with the cleaning nozzle 150 housed.

(Fourth Embodiment)
Next, a fourth embodiment will be described. In the fourth embodiment, a modified example of the jetting timing of wash water in advance pre-washing will be described with reference to FIGS. 13 and 14. Figure 1
3 and 14 are diagrams showing a modification example of the jetting timing of wash water in advance pre-washing.

In the above-described embodiment, the example in which the cleaning water or the sterilizing water is ejected from the toilet ejection port 220 after the cleaning nozzle 150 is advanced has been described. However, as shown in FIG. Cleaning water or sterilizing water may be jetted from the toilet outlet 220 while advancing the nozzle 150. Further, although FIG. 13 shows an example in which the pre-cleaning is performed while the cleaning nozzle 150 is advanced, it is possible to perform the same pre-cleaning operation while retracting the cleaning nozzle 150 after the cleaning nozzle 150 is advanced. Good.

Further, here, the cleaning water or the sterilizing water is continuously ejected while the cleaning nozzle 150 is advanced or retracted, but the control unit 600 advances or retracts the cleaning nozzle 150 and the cleaning water or the sterilization water is sterilized. Water may be spouted intermittently.

In addition, as shown in FIG. 14, the control unit 600 controls the operation of ejecting cleaning water or sterilizing water from the toilet outlet 220 after the cleaning nozzle 150 is advanced by a predetermined distance.
It may be repeated until 50 reaches the target position. In addition, the control unit 600 performs the operation of ejecting cleaning water or sterilizing water from the toilet outlet 220 after the cleaning nozzle 150 is advanced to the target position and then retracted by a predetermined distance. May be repeated until the storage position reaches the storage position.

In this way, the advance pre-cleaning may be performed at least when the cleaning nozzle 150 has advanced, and until the cleaning nozzle 150 reaches the target position or the storage position, the cleaning water is discharged from the toilet outlet 220. Alternatively, sterilizing water may be continuously or intermittently jetted.

(Other embodiments)
In each of the embodiments described above, an example in which one toilet spout 220 is provided for the cleaning nozzle 150 has been described, but a plurality of toilet spouts 220 may be provided for the cleaning nozzle 150. Good.

For example, the cleaning nozzle 150 has a first toilet outlet that ejects cleaning water or sterilizing water toward the front side of the bowl 11, and a first toilet nozzle that ejects cleaning water or sterilizing water toward the rear side of the bowl 11. A double toilet outlet may be provided. As a result, by performing advance pre-cleaning, cleaning water or sterilizing water can be supplied to a wide range on the front side and the rear side of the bowl portion 11.

Further effects and modifications can be easily derived by those skilled in the art. Therefore, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
